BALL BEARING.

Application filed May 11,

' application No. 3,254), of which the following is a specification.

This invention has for its object to provide an accurate ball bearing ofsuperior quality which is capable of being produced by expeditious andeconomical manufacturing operations.

he invention comprises the construction 1 -of one member of the bearlngfromv two rings which are situated on opposite sides' of the balls, anda sleeve or bush having flanged ends for retaining the rings, the saidsleeve or bush being formed with a peripheral indentation for adjustingand spacing the rings.

Also the invention comprisesthe employment between the aforesaid rings,of a separate ring with which the peripheral indentation of the sleeveor bush co-operates.

Referring to the accompanying sheet of explanatory drawings Figure 1 isa cross section of a ball bearing constructed in accordance with thisinvention, the two part bearing ring being the outer one.

Figure 2 is a cross section of a ball hearing in which the two partbearing ring is the inner one.

In carrying the inventioninto effect as shown in Figure Lthe innersingle bearing ring a is Inadein one piece, and is grooved to locatetheballs 5. The outer bearing ring is made in two parts a; These areheld toget-her by a shell or sleeve (5 having flanged ends. Theadjacentfaces of the rings a are chamfered near their outer peripheriesas shown, and into the annular recess'thus formed is forced an annularindentation 6 Specification of Letters Patent.

formed in the sleeve d, the indentation serving to produce the requiredspacing or adjustment of the rings 0.

The sleeve d (which may be made from steel tube or pressed from a steelsheet) is initially flanged at one end'only, and its cylindrical portionis plain. After the. parts have been assembled the other end of thesleeve is flanged, and by endwise pressure applied to the two flangesthe rings 0 are pressed tightly together. The dimensions of the partsare made such that in this operation the rings a are caused to bind onthe balls. A final adjusting operation is therefore necessary. This iseffected by the production in the shell of the annular or peripheralindentation e which forces the rings a apart or relieves the pressure'onthe balls sufliciently to give the required freedom to the balls. Inother words the spacing of the rings 0 is determined by the indentatione. By the use of the indentation variations likely to occur duringmanufacture in the dimensions of the rings 0 are readily compensated ina final adjusting operation. The great and costly refinement which isordinarily necessary in the production of the component. parts is thusavoided without sacrificing uniformity and accuracy-in the finishedproduct. Further the indentation serves to prevent the rings 0 frombeing subsequently pressed together by any endwise pressure which may beexerted on them in service.

The construction shown in Figure 2 differs from that of Figure 1 only inthat the inner ring is made in two parts, instead of the outer one, andthe said parts are held together by .a flanged bush. The corre-'sponding elements in the two constructions are indicated by the samereference letters.

Instead of making the indentation e bear directly on the adjacentinclined faces of the rings '0, it may becaused to act on a separate"split and contraotible' spacing ring f as shown in Figures 3 and 4. InFigure 3 one of the rings 0 is formed with a slightly 1nclinedintermediate face, whilst the corresponding face on the other ring isflat. The spacing ring f is made to a corresponding section. so thatwhen theinner periphery of the indentation e'in the sleeve bears on thering it is forced more or less between the rings 0 to produce the finaladjustment.

The

construction shown in'lBigure 4c differs from that of Figure 3 only inthat both of the intermediate faces of the rings and both outer faces ofthe ring 7 are inclined. If

desired the spacing ring f may be made of circular cross section.Instead of producing the indentation afterthe parts have been assembled,it may be formed before the sleeve or bush (Z is flanged;

the rings a being placed in position on opposite sides of theindentation, and the ends of the sleeve or bush turned over subsequently. Or the sleeve or bush may be flanged at one end and theindentation produced "after one rlng c has been inserted.-' is made byincreasing I claim as new and desire secure by Letters Patent is 1. lncombination, an inner race ring an outer race ring, a single row ofrolling elements arranged between said rings, one of said ringsconsisting of twoannular sections arranged on opposite pendicular lineintersecting the axis of said rings, said sections being provided withshaped surfaces engaging opposite sides of the first instance; the finaladjust-- sides of a per- I eachof said rolling elements, and a shellcooperating with said sections and'having end flanges engaging the outerside surfaces of the; sections, said shell being provided intermedi'teits ends with an annular depressed portion extending between said sectitie for preventing said sections from binding on the rolling elements.

- 2 A combination as claimed in claim 1 in which a spacing ring isarranged between said sectlons and engages the depressed por- ;tion ofsaid shell.

-3. A combination as claimed in claim 1 in which an expansible splitring is arranged between said sections and engages the depressed portionof said shell.

4:. A combination as claimed in claim 1 in which a spacing ring isarranged between said sections and has one of its sides beveled, and oneof said sectionsbeing provided with a corresponding beveled faceengaging the beveled surface of said spacing ring.

5. A combination as claimed in claim 1 in which the adjacent surfaces ofsaid sections are beveled, and an expansible spacing ring arrangedbetween said sections and having its opposite sides beveled, the beveledsides of said spacing ring engaging the beveled surfaces of saidsections. In testimony whereof l have signed my name to thisspecification.
